Consider the equilibrium: H₂(g) + CO₂(g) ≥ CO (g) + H₂0 (g) 1.59 at 1290 Kelvin. Calculate Ar Gº for this reaction. where Kp = Imagine you fill a reaction vessel with the following pressures: PH₂ = 0.25 bar; Pco₂ 0.25 bar; Pco = 0.66 bar; PH₂0 = 0.66 bar Calculate AG at these conditions. Does the reaction need to go forward or in the reverse direction to achieve equilibrium? Finally, calculate the equilibrium pressures of each gas in bars.
